    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 KrP?*yk  
    Bor_(eL^  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: I_#5gq  
    enableservice('AutomationServer', true) =~s+<9c]  
    enableservice('AutomationServer') o(}%b8 K  
    t=eI*M+>h  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 nh7_ jEX  
    F<h+d917  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: [qY yr  
    1. 在FRED脚本编辑界面找到参考. Q~.t8g/  
    2. 找到Matlab Automation Server Type Library |WUM=g7PC  
    3. 将名字改为MLAPP yC ?p,Ci,

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 dU_;2d$

    现在将脚本代码公布如下,此脚本执行如下几个步骤: lA4-ZQ2Zp[  
    1. 创建Matlab服务器。 >r X$E<B\  
    2. 移动探测面对于前一聚焦面的位置。 =x?WZMO  
    3. 在探测面追迹光线 .[eC w  
    4. 在探测面计算照度 Q(A$ >A  
    5. 使用PutWorkspaceData发送照度数据到Matlab IkmEctAU  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 @=z.^I30  
    7. 用Matlab画出照度数据 h+Lpj^<2a  
    8. 在Matlab计算照度平均值 ^?]-Q*w3Qs  
    9. 返回数据到FRED中 q%M~gp1
